The clinical and morphologic spectrum of optic nerve hypoplasia
Hellström A; Wiklund LM; Svensson EJournal of AAPOS 1999; 3: 212-220
PURPOSE: The purpose of this study was to characterize the clinical and morphological spectrum of all children referred for optic nerve hypoplasia to a tertiary referral hospital in Sweden during a nine-year period. SUBJECTS AND METHODS: A retrospective review was undertaken of the charts of 117 children (age range, 0.25-16 years), treated at the Children's Hospital, Göteborg between 1988 and 1996, after the diagnosis of optic nerve hypoplasia. Ocular fundus morphological condition was evaluated by digital image analysis of fundus photographs in 50 children, and neuroimaging performed in 57 children. RESULTS: Of the 117 children with optic nerve hypoplasia, 66 (56%) were boys and 51 (44%) were girls. Preterm birth occurred in 24 (20%), and 14 (12%) were born small for gestational age. Additional diagnoses, such as fetal alcohol syndrome, septo-optic dysplasia, perinatal adverse events, and neuropsychiatric disorders, were made in 88%; 7% had unilateral optic nerve hypoplasia. Most of the children had small optic disc, cup, and neuroretinal rim areas, as well as retinal vascular abnormalities; 75% were visually impaired, and a high incidence of nystagmus and strabismus was found among these children. CONCLUSIONS: This study indicates that optic nerve hypoplasia has a wide clinical and morphological spectrum and is associated with a broad range of disorders of the central nervous system. It is suggested that differences in the etiology and timing of the lesion as well as associated lesions may explain this spectrum of optic nerve hypoplasia in children.
